Patient engagement in a mobile health intervention to improve preparedness for prostate biopsy.

OBJECTIVE

We designed and implemented a peri-procedural text message (SMS) program for patients undergoing transrectal prostate biopsy and aimed to evaluate predictors of patient enrollment and engagement with the SMS program.

METHODS

We designed an SMS-based program with 8 messages containing web-based modules with educational content and reminders confirming MRI for fusion biopsy, antibiotic adherence, enema use, and anticoagulation cessation. Data on patient demographics, enrollment, and engagement with modules were collected from June 1, 2018 to February 28, 2021. Engagement was defined as a patient clicking a link delivered via SMS to access modules. We made multivariable models to identify predictors of patient enrollment and engagement.

RESULTS

Of the 1,760 prostate biopsies between June 2018 and March 2021, 1,383 (78.6%) were enrolled in SMS, 182 (10.3%) in email, 106 (6.0%) in both, and 240 (13.6%) were not enrolled. Of 1418 patients enrolled, 1,270 (89.6%) engaged with at least one module. African American patients had 50% lower odds of being enrolled (OR = 0.50, 95% CI 0.28-0.96; P = 0.03), but once enrolled there were no differences in engagement. Patients for whom English was not listed as their primary language had 60% lower odds of engagement (OR = 0.40, 95% CI 0.17-1.00, P = .04) and patients who were single or divorced had a 40% lower odds of engagement (OR = 0.60, 95% CI 0.41-0.91, P = 0.01).

CONCLUSIONS

A cohort of older men undergoing prostate biopsy were able to engage with a text message-based education and reminder program. Future efforts must address barriers to enrollment for Black or African American men and improve accessibility to non-English speaking patients.
